ABSTRACT:
The color printing of textile webs or structures such as carpets and tiles which are tufted or non-woven wherein the color is sublimatic dyestuff carried by an air permeable printing foil and this is placed over the textile structure with the dyestuff facing the textile structure. Heat is applied to vaporize the dyestuff and a pressure differential across the textile structure causes an air flow through the sheet structure and printing foil to affect penetration of the dye vapor into the structure. The dyestuff deposits on the textile fibres and filaments in the pattern it appeared on the printing foil. The said pressure differential is preferably produced by creating a vacuum at the side of the sheet structure opposite the printing foil.
